Yes it does. Bought Apple's 30-pin to Thunderbolt connector (more expensive than knock-offs on eBay as it has the DAC, digital audio converter, built into the tiny unit. Without this little unit only would charge not pass sound through. It does everything! Charges, plays music through the wireless FM broadcaster. I use muy Sirius app to access my account and play whatever. Also will play my own music in iTunes. Fortunately, I have a little Honda Civic Si that has an open storage slot in the dash directly below the radio. As a result, it gets excellent stereo reception without any static. Hope this helps :)))

This is an FM transmitter, meaning that you need to have an open and available FM frequency in your area to do this.
This product will not work without this, but most areas have one or two frequencies available
